GLYCAM and GAFF2 in LAMMPS

[Arun_Srikanth1]

Hello all

I am trying simulate a material with glycam and gaff2 forcefield together. These force fields differ in their 1-4 interactions and a single special bonds command may not serve my purpose. Is there any way that I can implement this in lammps or is there any feature like special bonds grouping based on atom types that I am not aware of where we can set variable scaling of 1-4 interactions for each excluded pair.

Thanks

Arun

Please see the documentation for pair style hybrid and the pair_modify command for available options.
